FOLDING TRESTLE.

Specification of Letters Patent.

Patented Aug. 2&, 1915.

Application filed February 2, 1915. Serial No. 5,750.

To all whom it may concern:

Be it known that 1, CHARLES C. HENsLEY, a citizen of the United States,residing at Alexandria, in the county of Madison, State of Indiana, haveinvented certain new and useful Improvements in Folding Trestles; and Ido hereby declare the following to be a full, clear, and eXactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to new and useful improvements in trestles.

The principal object of the invention is to provide a simple and noveltrestle which can be quickly and easily folded into a compact form sothat it may be readily carried about.

Another object is to provide a folding trestle which is simple inconstruction and which is strong and durable in use.

Other objects and advantages will be apparent from the followingdescription when taken in connection with the accompanying drawings.

In the drawings: Figure 1 is a side elevation of the trestle in openposition, Fig. 2 is an end view of the same, Fig. 3 is a verticallongitudinal sectional view, and Fig. 4: is a bottom plan view of thetrestle in folded position.

Referring now more particularly to the accompanying drawings, 10represents an elongated and inverted Ushaped bar which forms the upperbeam of the trestle. EX- tending transversely through each end of thebar is a bolt or pin 11, and mountedr on he lower portions of theselegsare pivotally connected together by means of the bracing links 13, theselinks being pivotally connected at their inner ends as shown at 14:. Oneof the links 13, adjacent its connection with the other link is formedwith a struck up and rolled tongue 15 through which passes anoscillatible pin 16. The inner end of this pin is pivotally connected tothe lower end of a link 18, as indicated at 17 said link being pivotallyconnected at its upper end to a link 19 which is pivotally mountedwithin the bar 10 at a suitable point inwardly of the pin 11. Theelements just described are duplicated at-the other end of the bar 10,as will be apparent from an inspection of the drawings. The pivotalpoint 14, and the pivotal connection between the links 18 and 19 are ofthe stop joint variety so that these pivots will not swing beyond theirfull open position, thus making rigid braces to hold the legs 12 apart,and braced from the bar 10.

To fold the trestle, the joint of the links 18 and 19 is brokendownwardly, and then the joint 14 broken upwardly, thus permit ting thelegs to be folded together and to be swung on the pin 11 upwardly withinthe hollow of the bar 10, the links 18 and 19 readily folding togetherand passing up into the hollow of the bar also. When thus folded thetrestle is in a small compact condition, and can be readily carriedabout.

Particular attention is called to the connection of the link 18 with thelink 13 so as to provide, in efi'ect, a swivel or universal oint, thuscompensating for the vertical movement of the link 13 and the inwardswing of the legs 12 toward folded position within the bar.

What is claimed is:

1. A trestle comprising a bar, legs mov- CHARLES C. HENSLEY.
